METDEEM High Efficiency DM140A Hydraulic Breaker Box Type FOR Excavator

The core advantages of the METDEEM DM140A box type breaker  equipped with an accumulator are presented in sections as follows

Significantly protect the hydraulic system of excavators

• The accumulator can effectively absorb and buffer the intense hydraulic shock and high-frequency pulses generated during the operation of the breaker, reducing the pressure peak transmitted back to the main pump and valve group of the excavator by approximately 30%.
• This significantly reduces the stress fatigue of the main engine’s hydraulic system, directly extending the service life of the core components of the excavator, and lowering its failure rate and maintenance costs.

Enhance the continuity and stability of the striking force

• The accumulator stores energy during the piston’s return stroke and releases it at the moment of impact, providing additional instantaneous flow replenishment for the hydraulic system.
• This makes each strike of the DM140A more full and powerful, reducing the sense of force attenuation under continuous rapid strikes, and thus achieving more sustained and stable operation efficiency when demolding concrete or breaking rocks.

Achieve the synergy of high efficiency and low noise

• The accumulator indirectly reduces some of the noise caused by sharp pressure fluctuations by smoothing out hydraulic pulsation.
• This forms a synergy effect with the original patented silent housing technology of the DM140A, reducing noise through both the internal hydraulic system and the external acoustic wrapping.
• Together, they achieve its outstanding low-noise performance as a “box type breaker “, making its environmental protection performance even more remarkable.

Reduce energy consumption and operating costs

• By recovering and reusing part of the hydraulic energy, accumulators help the system work more efficiently and can reduce the overflow loss of the hydraulic system to a certain extent.
• This means that under the condition of completing the same crushing volume, the load on the hydraulic system of the equipment is relatively smaller, which helps to Box Type Breaker reduce the fuel consumption of the excavator Box Type Breaker and achieve more economical operation.

Enhance the adaptability of the equipment under complex working conditions

• When dealing with materials of uneven hardnessor when frequent strikes are required, accumulators play a crucial role in “buffering” and “replenishing force”, ensuring the smooth operation of the equipment’s hydraulic system.
• This enhances the overall reliability and adaptability of the DM140A under complex and variable working conditions, reducing protective shutdowns of the equipment caused by excessive pressure fluctuations.

In summary, the accumulator is not only a component of the DM140A box type breaker , but also a key enabling system for it to achieve the comprehensive performance of “powerful, environmentally friendly, reliable and economical”.
It has comprehensively enhanced the core competitiveness of the product in the high-end construction market from multiple dimensions such as protecting the main unit, improving energy efficiency, and stabilizing output. Box Type Breaker
